FARM-GATE.

SPECIFICATION forming part of Letters Patent No. 377,479. dated February 7, 188 8.

Application filed April 16, 18m. Serial No. 235,132. (No model.) v

farm-gates described in the following specification and illustrated in the accompanying drawings, similar letters referring to similar parts I thronghont'the several views.

Figure l is a perspective view of my, gate with all its parts in position, as it will appear when erected. Fig. 2 is an upright front elevation of the catch-post A; Fig. 3, a side elevation of the double-crank hinge-rod B; Fig. 4., a top view of the eyebolt b,- Fig. 5, a perspective view of the ,T-lever G, with luneshaped cord-rack attached.

G is the main post, into which are firmly -2 fastened the eyebolts b and b at g and g, the

eyes of which receive and allow to turn the double-crank hinge-rod B. is-a round piece of iron ofsnfficient length I and thickness, is bent so as to form two opo posing cranks, b and bflwhich turn in the eyes f and f of the-hinge-strap's F and F. Just below the crank b is the collar bfl'which rests on the eyebolt b and serves as a bearing or support to the'rod B.

tached the collar b gwhich serves/as bearing or support to the gateL, by means of the hingestrap F, which rests thereon. At the proper distance between the two cranks and in the direction. of the crank'bfland immediately oppositeto the direction of the crank b is rigidly attached to the rod-B the piece B, of sufficient length and strength to serve as a lever inopening or closing the gate L. The upper My invention relates to the improvement'in This rod, which- To the lower end of crank-bearing b is at end, I), of the rod B is made square tofit into main bar, 0 having at one end the heads, in I which is made the square eye 0, and at the other end, at its middlepoint and at right an gles with the bar 0 the bar ciwhich completes the T shape. This cross-bar 0 has at its ends the crosslugs c and 0 standing vertical and at right anglesto the bar c which is placed horizontally. The rack 0 consists of two wires, c and c, bent lunate in form andhaving their extremities firmly fastened to the cross-lugs c i and c by the rivets or bolts 0 0?. These lunewires are joined by five or more. cross-wires,

0 curved inwardly, so as to form a groove or channel to receive the cords I and I.

I The cord I, having one end fastened to the I crossbar a of the T-lever O at'z', then passes along the groove of the wirecord-rack O to 4 the sheave E; attached tothe upper end of the post H at h, entering the holee passing over the sheave fully, and coming out of the hole e", and is held taut by the weight K, attached to the other end at In a similar manner, butin an opposite direction, the cord 1, fast ened at i, passes'along the cord-rack oventhe other.v sheave E at h, andis held taut by the weight K, attached to the end at '5. The holes 0. and e in the cap-rings serve as guides to keep the cords in the grooves of the sheave-pulleys.

The operation of my invention is as follows:

Pulling'downward on the cord I, as indicated to the right and forward, andthe resultof the 8 5 combined movement of these 'cranks'will be to elevate the front part, L, of the gate L, carrying with it the fixed latch D,- until the latch-, roll d will pass above the partition a of the latch-catch A,when the actionof the lever B,

exerted in the same direction, will be to swing I open the gate L in the direction indicatedby the arrow 8, toward the catch-post H, to which is fastened a catch, h", which will receive the 1atch-rolld and hold the gate L opened. A 5

downward pull on the cord I, as indicated by arrowi, will cause these same movementsto be executed in an opposite'direction, the latch-' catch receiving the latch-roll d and holding the gateL closed.

Having fully described my invention and its operation, what I claim as new, and desire to secure by Letters Patent, is

1. The combination,with a gate, of a hingerod, B, having two opposing cranks, b and b the two collars b and b the rigid swing-lever B, and the square end If, and working in the eyebolts b and b, substantially as set forth.

2. Theccombination, with a gate and hingerod, as described, of a T-lever and cord-rack 0, having the horizontal bar 0 the head 0, pierced by the square hole 0, the cross-bar 0 having at its extremities the vertical cross-lugs c and 0", having the holes 11 and i the two lane ISAAC BURKHOLDER.
